I hear it on pro-433 but not on 536, I don't know for what reason
As I remember, EDACS trunked isn't used here since a decade or more ago, it has a control channel with a constant datasignalling that should be easy to check.
Push CHANNEL to stop scanning. Enter the frequency of LCN1 that probably are the control channel. Push Channel again.
Turn down squelch to 0 and turn the dial 3-4 steps to move off frequency and then back again. You should hear noise when you go to another frequency and the control data on the exact frequency. It could also mute the audio and start to decode the datastream after just a brief moment.
Do the same with all frequencies to catch the control channel if it have moved to another LCN.
If you only get noise and no control channel data you have no reception and you will need to check the antenna or your position and location of the scanner antenna.
If you do hear control data and it mutes the audio you have to check that service types and LCN's are the correct ones in your programming. But you first need to receive a radio signal before looking into that.
